What is the significance of basement membrane? View Solution What is meant by semipermeable membrane ? Give one example each for natural and artificial membrane. View Solution Osmosis is the spontaneous flow through a semi-permeable membrane of ...
What is plant cell biology? What part of the cell is selectively permeable? What structure provides support and protection for plant cells? What part of a plant cell covers and protects it? What are plastids in a plant cell? What kind of cells make up the basement membrane?
A membrane that is permeable isn’t usually open like a sieve, but is more or less penetrable by certain substances under certain conditions. Cell Membrane Basics Cell membranes have selective permeability, meaning that they will allow certain substances to pass while forming a barrier against ...
ait occurs whenever water molecules diffuse from a region of higher concentration through a selectively permeable membrane,such as a cell membrane. 它发生,每当水分子从更高的浓度的区域散开通过一个有选择性地有渗透性的膜,例如细胞膜。[translate] ...
Membrane proteins are as the name suggests, proteins embedded or attached to the membrane. Proteins are useful macromolecules because they can serve a variety of functions and the location of these proteins suggests something about their function....
Nucleus is the organelle which encloses the genetic material in eukaryotic cell. It is a double membrane bound organelle. It also contains RNA and protein. It is the site of replication of DNA and formation of RNA.Answer and Explanation: Structure of Nucleus...

Two solutions of differing glucose concentrations are placed in a container separated by a selectively permeable membrane that restricts large molecules like glucose but allows the free diffusion of water. What will be the glucose concentration in the con ...
Why is a cell membrane described as a 'fluid mosaic'? Membranes are selectively permeable. What does this mean? If cell membranes WEREN'T selectively permeable to compounds like sugars and amino acids, what would happen to the nutrients that the...
Turgor pressure isthe hydrostatic pressure in excess of ambient atmospheric pressurewhich can build up in living, walled cells. Turgor is generated through osmotically driven inflow of water into cells across a selectively permeable membrane; this membrane is typically the plasma membrane. ...
